Hoping someone can help. I recently tried my spare key and found it would not start the car. The key is the original one supplied with the car and still has the tags with the security numbers. The remote locking is working fine.

Two questions:

I had the dash pod replaced under warranty a year ago, could this have affected the immobiliser system?

Do I have to go back to the dealer to have it reprogrammed, and is it easier and cheaper as I have the codes that came with the keys?

If all keys were not available to the dealer when the dash panel was replaced they wouldn't have been coded to the immobiliser.

Thanks for that. I thought I had read somewhere the dash pod was involved. I'll go back to the dealer that replaced it. Would have been better if they had asked for the spare key at the time.
